Just last night a new version of Android started rolling out for Sprint users of the Nexus 5. Strangely, a previously unmentioned version of Android, version 4.4.4 just pushed out OTA to the Sprint Nexus 5 (and possibly other brands of Nexus products). We haven't seen hide nor hair of this update before it actually started hitting phones, so we don't even know what it fixes. After doing some digging, we found the details on the ParanoidAndroid Google+ page. Here's a quote,
4.4 FINAL / ANDROID 4.4.4
This week at PA headquarters we worked very hard to bring you the most stable experience ever since 4+.
Too many hot fixes have been merged today, along with some new goodies.
What does 4.4 Final mean?
Current featured branch reached final stable state. Doesn’t mean at all that development has stopped You can just flash this, and feel safe.
KITKAT UPSTREAM
Android 4.4.4 upstream tag has been merged into our source.
VOLUME PANEL
The Volume Panel has been re-designed as you can see in the image below to be inline with hover, be less intrusive and more beautiful.
HOVER
Hover UI/UX has been reworked a bit for tablet users: Hover will not take the whole screen width, but it will respect notification size. Also status bar isn’t hidden when hover shows and you can pull it down when you want, as you touch status bar Hover will be dismissed to not overload on top of status bar expanded state. Another awesome thing is that un-dismissible notifications cases like screenshots etc have been solved (yea is true). Last but not least the marriage with ticker view has been reworked, when hover is enabled and you receive notifications from foreground app they will not be shown in Hover but in ticker.
PIE
Fixed a couple of issues regarding repositioning. Also, Pie now follows same behavior of navigation bar on phone when in landscape, sticks at right. Last but not least Pie is now themeable by external xml resources, by Theme Engine.
PEEK
As for Peek App our Native Peek got some love on sensors side. They should work better now. You can find latest Peek App with advanced features on Play Store, check link below.
THEME ENGINE
Merged upstream changes and added style support to Dialer app, IME switcher alert dialog and many more.
BATTERY TILE AND STATUS BAR INDICATOR
Added colorizing support for all components for both circle and stock look. Themers can play with everything now
